| Abstract: | The pressure measuring was achieved using the developed light-intensity-modulation fiber pressure testing instrument, which was composed by amesdial and diaphragm pressure sensor. The testing curve has been obtained, which shows the linearity of the pressure from the pressure sensor and the displacement from the convoluted diaphragm. The developed fiber pressure testing immanent has been calibrated with pressure test beard, and its measurement precision can reach 0.7 % in 0 - 3 MPa measurement range, by comparing and analyzing the test result. |
